(93, 130, 6512943)-Net in Base 9 — Upper bound on s
There is no (93, 130, 6512944)-net in base 9, because
- 1 times m-reduction [i] would yield (93, 129, 6512944)-net in base 9, but
- the generalized Rao bound for nets shows that 9m ≥ 1251 076425 847928 341712 156910 653980 408695 636622 291399 485363 064673 974135 790403 016698 870875 894315 842797 312915 278655 602492 342529 > 9129 [i]
